g) (x - 9)3 : 24 = 9
h) 19x + 153 = 7
​

Answer 1

Respuesta:

tambien nesesitoooooooooooooooooo

Answer 2

Respuesta:

√(169)-X^2 = -51 ; √(169) = 13

13-X^2 = -51

13-X^2-13 = -51-13

-X^2 = -64

-X^2/-1 = -64/-1

X^2 = 64

X^2 - 64 = 64-64

( X^2 - 64 ) = 0

( X-8 ) ( X+8 ) = 0

X1 = 8 y X2 = -8

(X-9)3/24 = 9

( 3X-3 )/24 = 9

24((3X-3)/24) = 9(24)

3X-3 = 216

3X-3-216 = 216-216

3X-219 = 0

-219 = -3X

-219/-1 = -3X/-1

219 = 3X

219/3 = 3X/3

73 = X

X= 73

19X+153 = 7

19X+153-7 = 7-7

19X + 146 = 0

19X = -146

19X/19 = -146/19

X = -146/19
